You need to subscribe to the observable and pass a callback that processes emitted values

this.myService.getConfig().subscribe(val => console.log(val));

Chapter 4.8 Block Structure in K&R's The C Programming Language 2.Ed.:

An automatic variable declared and initialized in a block is initialized each time the block is entered.

I might have missed seeing the relevant description in the book like:

An automatic variable declared and initialized in a block is allocated only one time before the block is entered.

But a simple test can prove the assumption held:

 #include <stdio.h>                                                                                                    

 int main(int argc, char *argv[]) {                                                                                    
     for (int i = 0; i < 2; i++) {                                                                                     
         for (int j = 0; j < 2; j++) {                                                                                 
             int k;                                                                                                    
             printf("%p\n", &k);                                                                                       
         }                                                                                                             
     }                                                                                                                 
     return 0;                                                                                                         
 }                                                                                                                     

Just make sure put single space before and after "and" Keyword..

What about:

//true if it doesn't contain letters
bool result = hello.Any(x => !char.IsLetter(x));

If you are using CocoaPods and you want to disable Bitcode for all libraries, use the following command in the Podfile

post_install do |installer|
    installer.pods_project.targets.each do |target|
        target.build_configurations.each do |config|
            config.build_settings['ENABLE_BITCODE'] = 'NO'
        end
    end
end

Include this line on top of your test class

@PrepareForTest({ First.class })

One solution (though not very pretty) is to use Apache common List/Set mutation

import org.apache.commons.collections.list.SetUniqueList;

final List<Long> vertexes=SetUniqueList.setUniqueList(new LinkedList<>());

it is a list without duplicates

https://commons.apache.org/proper/commons-collections/javadocs/api-3.2.2/index.html?org/apache/commons/collections/list/SetUniqueList.html

For my case, none of the above solutions worked.

However since I am using the Child Fragment Manager in a Fragment, the following was used:

Fragment f = getChildFragmentManager().getFragments().get(viewPager.getCurrentItem());

This will only work if your fragments in the Manager correspond to the viewpager item.

Yes. It is done with a filter on the appender.

Here is the appender configuration I normally use, limited to only INFO level.

<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
  <file value="${HOMEDRIVE}\\PI.Logging\\PI.ECSignage.${COMPUTERNAME}.log" />
  <appendToFile value="true" />
  <maxSizeRollBackups value="30" />
  <maximumFileSize value="5MB" />
  <rollingStyle value="Size" />     <!--A maximum number of backup files when rolling on date/time boundaries is not supported. -->
  <staticLogFileName value="false" />
  <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
  <layout type="log4net.Layout.PatternLayout">
        <param name="ConversionPattern" value="%date{yyyy-MM-dd HH:mm:ss.ffff} [%2thread] %-5level %20.20type{1}.%-25method at %-4line| (%-30.30logger) %message%newline" />
  </layout>

  <filter type="log4net.Filter.LevelRangeFilter">
        <levelMin value="INFO" />
        <levelMax value="INFO" />
  </filter>
</appender>    

Looking at the neural network from the outside, it is just a function that takes some arguments and produces a result. As with all functions, it has a domain (i.e. a set of legal arguments). You have to normalize the values that you want to pass to the neural net in order to make sure it is in the domain. As with all functions, if the arguments are not in the domain, the result is not guaranteed to be appropriate.

The exact behavior of the neural net on arguments outside of the domain depends on the implementation of the neural net. But overall, the result is useless if the arguments are not within the domain.

OutputDebugString function will do it.

example code

    void CClass::Output(const char* szFormat, ...)
{
    char szBuff[1024];
    va_list arg;
    va_start(arg, szFormat);
    _vsnprintf(szBuff, sizeof(szBuff), szFormat, arg);
    va_end(arg);

    OutputDebugString(szBuff);
}

Anonymous FTP usage is covered by RFC 1635: How to Use Anonymous FTP:

What is Anonymous FTP?

Anonymous FTP is a means by which archive sites allow general access to their archives of information. These sites create a special account called "anonymous".

…

Traditionally, this special anonymous user account accepts any string as a password, although it is common to use either the password "guest" or one's electronic mail (e-mail) address. Some archive sites now explicitly ask for the user's e-mail address and will not allow login with the "guest" password. Providing an e-mail address is a courtesy that allows archive site operators to get some idea of who is using their services.

These are general recommendations, though. Each FTP server may have its own guidelines.

For sample use of the ftp command on anonymous FTP access, see appendix A:

I think this is the best way to get the month name when you have the month number

Select DateName( month , DateAdd( month , @MonthNumber , 0 ) - 1 )

Or

Select DateName( month , DateAdd( month , @MonthNumber , -1 ) )

using remove() method you can able to remove.

getLogout(data){
        return this.sessionModel
        .remove({session_id: data.sid})
        .exec()
        .then(data =>{
            return "signup successfully"
        })
    }

I had a similar problem and just found a way to solve it (by single-stepping through log4j-extras source, no less...)

The good news is that, unlike what's written everywhere, it turns out that you actually CAN configure TimeBasedRollingPolicy using log4j.properties (XML config not needed! At least in versions of log4j >1.2.16 see this bug report)

Here is an example:

log4j.appender.File = org.apache.log4j.rolling.RollingFileAppender
log4j.appender.File.rollingPolicy = org.apache.log4j.rolling.TimeBasedRollingPolicy
log4j.appender.File.rollingPolicy.FileNamePattern = logs/worker-${instanceId}.%d{yyyyMMdd-HHmm}.log

BTW the ${instanceId} bit is something I am using on Amazon's EC2 to distinguish the logs from all my workers -- I just need to set that property before calling PropertyConfigurator.configure(), as follow:

p.setProperty("instanceId", EC2Util.getMyInstanceId());
PropertyConfigurator.configure(p);

You need to do two things:

1. Rename and re-order the factor levels before the plot
2. Rename the title of each legend to the same title

The code:

dtt$model <- factor(dtt$model, levels=c("mb", "ma", "mc"), labels=c("MBB", "MAA", "MCC"))

library(ggplot2)
ggplot(dtt, aes(x=year, y=V, group = model, colour = model, ymin = lower, ymax = upper)) +
  geom_ribbon(alpha = 0.35, linetype=0)+ 
  geom_line(aes(linetype=model), size = 1) +       
  geom_point(aes(shape=model), size=4)  +      
  theme(legend.position=c(.6,0.8)) +
  theme(legend.background = element_rect(colour = 'black', fill = 'grey90', size = 1, linetype='solid')) +
  scale_linetype_discrete("Model 1") +
  scale_shape_discrete("Model 1") +
  scale_colour_discrete("Model 1")

However, I think this is really ugly as well as difficult to interpret. It's far better to use facets:

ggplot(dtt, aes(x=year, y=V, group = model, colour = model, ymin = lower, ymax = upper)) +
  geom_ribbon(alpha=0.2, colour=NA)+ 
  geom_line() +       
  geom_point()  +      
  facet_wrap(~model)

It's '\u0000'. See here for more information.

`CREATE TRIGGER `category_before_ins_tr` BEFORE INSERT ON `category`
  FOR EACH ROW
BEGIN
    **SET @tableId= (SELECT id FROM dummy LIMIT 1);**

END;`;

As mentioned in the comments, some labels in y_test don't appear in y_pred. Specifically in this case, label '2' is never predicted:

>>> set(y_test) - set(y_pred)
{2}

This means that there is no F-score to calculate for this label, and thus the F-score for this case is considered to be 0.0. Since you requested an average of the score, you must take into account that a score of 0 was included in the calculation, and this is why scikit-learn is showing you that warning.

This brings me to you not seeing the error a second time. As I mentioned, this is a warning, which is treated differently from an error in python. The default behavior in most environments is to show a specific warning only once. This behavior can be changed:

import warnings
warnings.filterwarnings('always')  # "error", "ignore", "always", "default", "module" or "once"

If you set this before importing the other modules, you will see the warning every time you run the code.

There is no way to avoid seeing this warning the first time, aside for setting warnings.filterwarnings('ignore'). What you can do, is decide that you are not interested in the scores of labels that were not predicted, and then explicitly specify the labels you are interested in (which are labels that were predicted at least once):

>>> metrics.f1_score(y_test, y_pred, average='weighted', labels=np.unique(y_pred))
0.91076923076923078

The warning is not shown in this case.

You could do it with jsoup http://jsoup.org/

Whitelist whitelist = Whitelist.none();
String cleanStr = Jsoup.clean(yourText, whitelist);

Update! New & improved! Find plugin @ GitHub!

On another note, while that method is simple, I've created a jQuery plug (found at this jsFiddle, just copy and past code between comment lines) that makes changing the cursor on any element as simple as $("element").cursor("pointer").

But that's not all! Act now and you'll get the hand functions position & ishover for no extra charge! That's right, 2 very handy cursor functions ... FREE!

They work as simple as seen in the demo:

$("h3").cursor("isHover"); // if hovering over an h3 element, will return true, 
    // else false
// also handy as
$("h2, h3").cursor("isHover"); // unless your h3 is inside an h2, this will be 
    // false as it checks to see if cursor is hovered over both elements, not just the last!
//  And to make this deal even sweeter - use the following to get a jQuery object
//       of ALL elements the cursor is currently hovered over on demand!
$.cursor("isHover");

Also:

$.cursor("position"); // will return the current cursor position as { x: i, y: i }
    // at anytime you call it!

Supplies are limited, so Act Now!

I decided to compact everything I learned into one file. There's a lot to take in here especially compared to before RC5. Note that this source file includes the AppModule and AppComponent.

See https://polarssl.org/kb/cryptography/asn1-key-structures-in-der-and-pem (search the page for "BEGIN RSA PRIVATE KEY") (archive link for posterity, just in case).

BEGIN RSA PRIVATE KEY is PKCS#1 and is just an RSA key. It is essentially just the key object from PKCS#8, but without the version or algorithm identifier in front. BEGIN PRIVATE KEY is PKCS#8 and indicates that the key type is included in the key data itself. From the link:

The unencrypted PKCS#8 encoded data starts and ends with the tags:

-----BEGIN PRIVATE KEY-----
BASE64 ENCODED DATA
-----END PRIVATE KEY-----

Within the base64 encoded data the following DER structure is present:

PrivateKeyInfo ::= SEQUENCE {
  version         Version,
  algorithm       AlgorithmIdentifier,
  PrivateKey      BIT STRING
}

AlgorithmIdentifier ::= SEQUENCE {
  algorithm       OBJECT IDENTIFIER,
  parameters      ANY DEFINED BY algorithm OPTIONAL
}

So for an RSA private key, the OID is 1.2.840.113549.1.1.1 and there is a RSAPrivateKey as the PrivateKey key data bitstring.

As opposed to BEGIN RSA PRIVATE KEY, which always specifies an RSA key and therefore doesn't include a key type OID. BEGIN RSA PRIVATE KEY is PKCS#1:

RSA Private Key file (PKCS#1)

The RSA private key PEM file is specific for RSA keys.

It starts and ends with the tags:

-----BEGIN RSA PRIVATE KEY-----
BASE64 ENCODED DATA
-----END RSA PRIVATE KEY-----

Within the base64 encoded data the following DER structure is present:

RSAPrivateKey ::= SEQUENCE {
  version           Version,
  modulus           INTEGER,  -- n
  publicExponent    INTEGER,  -- e
  privateExponent   INTEGER,  -- d
  prime1            INTEGER,  -- p
  prime2            INTEGER,  -- q
  exponent1         INTEGER,  -- d mod (p-1)
  exponent2         INTEGER,  -- d mod (q-1)
  coefficient       INTEGER,  -- (inverse of q) mod p
  otherPrimeInfos   OtherPrimeInfos OPTIONAL
}

Here is an extension/edit of VonCs solution just in case someone doesn´t want to go through the hassle of implementing their own filter to do this. It also shows how to output a JAXB element without the namespace present. This is all accomplished using a SAX Filter.

Filter implementation:

import org.xml.sax.Attributes;
import org.xml.sax.SAXException;

import org.xml.sax.helpers.XMLFilterImpl;

public class NamespaceFilter extends XMLFilterImpl {

    private String usedNamespaceUri;
    private boolean addNamespace;

    //State variable
    private boolean addedNamespace = false;

    public NamespaceFilter(String namespaceUri,
            boolean addNamespace) {
        super();

        if (addNamespace)
            this.usedNamespaceUri = namespaceUri;
        else 
            this.usedNamespaceUri = "";
        this.addNamespace = addNamespace;
    }



    @Override
    public void startDocument() throws SAXException {
        super.startDocument();
        if (addNamespace) {
            startControlledPrefixMapping();
        }
    }



    @Override
    public void startElement(String arg0, String arg1, String arg2,
            Attributes arg3) throws SAXException {

        super.startElement(this.usedNamespaceUri, arg1, arg2, arg3);
    }

    @Override
    public void endElement(String arg0, String arg1, String arg2)
            throws SAXException {

        super.endElement(this.usedNamespaceUri, arg1, arg2);
    }

    @Override
    public void startPrefixMapping(String prefix, String url)
            throws SAXException {


        if (addNamespace) {
            this.startControlledPrefixMapping();
        } else {
            //Remove the namespace, i.e. don´t call startPrefixMapping for parent!
        }

    }

    private void startControlledPrefixMapping() throws SAXException {

        if (this.addNamespace && !this.addedNamespace) {
            //We should add namespace since it is set and has not yet been done.
            super.startPrefixMapping("", this.usedNamespaceUri);

            //Make sure we dont do it twice
            this.addedNamespace = true;
        }
    }

}

This filter is designed to both be able to add the namespace if it is not present:

new NamespaceFilter("http://www.example.com/namespaceurl", true);

and to remove any present namespace:

new NamespaceFilter(null, false);

The filter can be used during parsing as follows:

//Prepare JAXB objects
JAXBContext jc = JAXBContext.newInstance("jaxb.package");
Unmarshaller u = jc.createUnmarshaller();

//Create an XMLReader to use with our filter
XMLReader reader = XMLReaderFactory.createXMLReader();

//Create the filter (to add namespace) and set the xmlReader as its parent.
NamespaceFilter inFilter = new NamespaceFilter("http://www.example.com/namespaceurl", true);
inFilter.setParent(reader);

//Prepare the input, in this case a java.io.File (output)
InputSource is = new InputSource(new FileInputStream(output));

//Create a SAXSource specifying the filter
SAXSource source = new SAXSource(inFilter, is);

//Do unmarshalling
Object myJaxbObject = u.unmarshal(source);

To use this filter to output XML from a JAXB object, have a look at the code below.

//Prepare JAXB objects
JAXBContext jc = JAXBContext.newInstance("jaxb.package");
Marshaller m = jc.createMarshaller();

//Define an output file
File output = new File("test.xml");

//Create a filter that will remove the xmlns attribute      
NamespaceFilter outFilter = new NamespaceFilter(null, false);

//Do some formatting, this is obviously optional and may effect performance
OutputFormat format = new OutputFormat();
format.setIndent(true);
format.setNewlines(true);

//Create a new org.dom4j.io.XMLWriter that will serve as the 
//ContentHandler for our filter.
XMLWriter writer = new XMLWriter(new FileOutputStream(output), format);

//Attach the writer to the filter       
outFilter.setContentHandler(writer);

//Tell JAXB to marshall to the filter which in turn will call the writer
m.marshal(myJaxbObject, outFilter);

This will hopefully help someone since I spent a day doing this and almost gave up twice ;)

The answer to your problem is easy: replace the current Fragment with the new Fragment and push transaction onto the backstack. This preserves back button behaviour...

Creating a new Activity really defeats the whole purpose to use fragments anyway...very counter productive.

@Override
public void onClick(View v) {
    // Create new fragment and transaction
    Fragment newFragment = new chartsFragment(); 
    // consider using Java coding conventions (upper first char class names!!!)
    FragmentTransaction transaction = getFragmentManager().beginTransaction();

    // Replace whatever is in the fragment_container view with this fragment,
    // and add the transaction to the back stack
    transaction.replace(R.id.fragment_container, newFragment);
    transaction.addToBackStack(null);

    // Commit the transaction
    transaction.commit(); 
}

Nope. You could have a function to make it more concise each place you use it, but in the end, the work done would be the same (plus the overhead of the function call, until/unless HotSpot moved it inline — to help it with that, make the functon static final).

You could use print_r and html interpret it to convert it into a string with newlines like this:

$arraystring = print_r($your_array, true); 

$arraystring = '<pre>'.print_r($your_array, true).'</pre>';

Or you could mix many arrays and vars if you do this

ob_start();
print_r($var1);
print_r($arr1);
echo "blah blah";
print_r($var2);
print_r($var1);
$your_string_var = ob_get_clean();

You have extra brackets in Hours property;

public  object Hours { get; set; }}

There is my working solution for sending image with post, using apache http libraries (very important here is boundary add It won't work without it in my connection):

            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);
            byte[] imageBytes = baos.toByteArray();

            HttpClient httpclient = new DefaultHttpClient();
            HttpPost httpPost = new HttpPost(StaticData.AMBAJE_SERVER_URL + StaticData.AMBAJE_ADD_AMBAJ_TO_GROUP);

            String boundary = "-------------" + System.currentTimeMillis();

            httpPost.setHeader("Content-type", "multipart/form-data; boundary="+boundary);

            ByteArrayBody bab = new ByteArrayBody(imageBytes, "pic.png");
            StringBody sbOwner = new StringBody(StaticData.loggedUserId, ContentType.TEXT_PLAIN);
            StringBody sbGroup = new StringBody("group", ContentType.TEXT_PLAIN);

            HttpEntity entity = MultipartEntityBuilder.create()
                    .setMode(HttpMultipartMode.BROWSER_COMPATIBLE)
                    .setBoundary(boundary)
                    .addPart("group", sbGroup)
                    .addPart("owner", sbOwner)
                    .addPart("image", bab)
                    .build();

            httpPost.setEntity(entity);

            try {
                HttpResponse response = httpclient.execute(httpPost);
                ...then reading response

Following code prints names of classes in specified namespace defined in current assembly.
As other guys pointed out, a namespace can be scattered between different modules, so you need to get a list of assemblies first.

string nspace = "...";

var q = from t in Assembly.GetExecutingAssembly().GetTypes()
        where t.IsClass && t.Namespace == nspace
        select t;
q.ToList().ForEach(t => Console.WriteLine(t.Name));

This works:

SELECT STR_TO_DATE(dateColumn, '%c/%e/%Y %r') FROM tabbleName WHERE 1

You could use if(number >= 0). The fact that you use int number = input.nextInt(); makes sure that it has to be an Integer.

If you have access to a linux box with mdbtools installed, you can use this Bash shell script (save as mdbconvert.sh):

#!/bin/bash

TABLES=$(mdb-tables -1 $1)

MUSER="root"
MPASS="yourpassword"
MDB="$2"

MYSQL=$(which mysql)

for t in $TABLES
do
    $MYSQL -u $MUSER -p$MPASS $MDB -e "DROP TABLE IF EXISTS $t"
done

mdb-schema $1 mysql | $MYSQL -u $MUSER -p$MPASS $MDB

for t in $TABLES
do
    mdb-export -D '%Y-%m-%d %H:%M:%S' -I mysql $1 $t | $MYSQL -u $MUSER -p$MPASS $MDB
done

To invoke it simply call it like this:

./mdbconvert.sh accessfile.mdb mysqldatabasename

It will import all tables and all data.

As you read through the examples below, just keep in mind this difference

true === true // true
"string" === true // false
1 === true // false
{} === true // false

But

Boolean("string") === true // true
Boolean(1) === true // true
Boolean({}) === true // true

1. expect(statement).toBe(true)

Assertion passes when the statement passed to expect() evaluates to true

expect(true).toBe(true) // pass
expect("123" === "123").toBe(true) // pass

In all other cases cases it would fail

expect("string").toBe(true) // fail
expect(1).toBe(true); // fail
expect({}).toBe(true) // fail

Even though all of these statements would evaluate to true when doing Boolean():

So you can think of it as 'strict' comparison

2. expect(statement).toBeTrue()

This one does exactly the same type of comparison as .toBe(true), but was introduced in Jasmine recently in version 3.5.0 on Sep 20, 2019

3. expect(statement).toBeTruthy()

toBeTruthy on the other hand, evaluates the output of the statement into boolean first and then does comparison

expect(false).toBeTruthy() // fail
expect(null).toBeTruthy() // fail
expect(undefined).toBeTruthy() // fail
expect(NaN).toBeTruthy() // fail
expect("").toBeTruthy() // fail
expect(0).toBeTruthy() // fail

And IN ALL OTHER CASES it would pass, for example

expect("string").toBeTruthy() // pass
expect(1).toBeTruthy() // pass
expect({}).toBeTruthy() // pass

You can also use Criteria.DISTINCT_ROOT_ENTITY with Hibernate HQL query as well.

Example:

Query query = getSession().createQuery("from java_pojo_name");
query.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY);
return query.list();

Keep in mind that the Rewrite engine only kicks in once the HTTP request has been received - which means you would still need a certificate, in order for the client to set up the connection to send the request over!

However if the backup machine will appear to have the same hostname (as far as the client is concerned), then there should be no reason you can't use the same certificate as the main production machine.

If, after reading the other questions and viewing the links mentioned in the comment sections, you still can't figure it out, read on.

First of all, where you're going wrong is the offset.

It should look more like this...

set mydate=%date:~10,4%%date:~6,2%/%date:~4,2%
echo %mydate%

If the date was Tue 12/02/2013 then it would display it as 2013/02/12.

To remove the slashes, the code would look more like

set mydate=%date:~10,4%%date:~7,2%%date:~4,2%
echo %mydate%

which would output 20130212

And a hint for doing it in the future, if mydate equals something like %date:~10,4%%date:~7,2% or the like, you probably forgot a tilde (~).

Building on the answer given above with the single line Tree using defaultdict, you can make it a class. This will allow you to set up defaults in a constructor and build on it in other ways.

class Tree(defaultdict):
    def __call__(self):
        return Tree(self)

    def __init__(self, parent):
        self.parent = parent
        self.default_factory = self

This example allows you to make a back reference so that each node can refer to its parent in the tree.

>>> t = Tree(None)
>>> t[0][1][2] = 3
>>> t
defaultdict(defaultdict(..., {...}), {0: defaultdict(defaultdict(..., {...}), {1: defaultdict(defaultdict(..., {...}), {2: 3})})})
>>> t[0][1].parent
defaultdict(defaultdict(..., {...}), {1: defaultdict(defaultdict(..., {...}), {2: 3})})
>>> t2 = t[0][1]
>>> t2
defaultdict(defaultdict(..., {...}), {2: 3})
>>> t2[2]
3

Next, you could even override __setattr__ on class Tree so that when reassigning the parent, it removes it as a child from that parent. Lots of cool stuff with this pattern.

you can try following code to delete local storage:

delete localStorage.myPageDataArr;

You can put this configuration in your settings.xml file:

            <repository>
                <id>mvnrepository</id>
                <url>http://repo1.maven.org/maven2</url>
                <snapshots>
                    <enabled>false</enabled>
                </snapshots>
                <releases>
                    <enabled>true</enabled>
                </releases>
            </repository>

In most of the companies they required a common functionality for multiple dropdownlist for all the pages. Just call the functions or pass your (DropDownID,JsonData,KeyValue,textValue)

    <script>

        $(document).ready(function(){

            GetData('DLState',data,'stateid','statename');
        });

        var data = [{"stateid" : "1","statename" : "Mumbai"},
                    {"stateid" : "2","statename" : "Panjab"},
                    {"stateid" : "3","statename" : "Pune"},
                     {"stateid" : "4","statename" : "Nagpur"},
                     {"stateid" : "5","statename" : "kanpur"}];

        var Did=document.getElementById("DLState");

        function GetData(Did,data,valkey,textkey){
          var str= "";
          for (var i = 0; i <data.length ; i++){

            console.log(data);


            str+= "<option value='" + data[i][valkey] + "'>" + data[i][textkey] + "</option>";

          }
          $("#"+Did).append(str);
        };    </script>

</head>
<body>
  <select id="DLState">
  </select>
</body>
</html>

Put in the URL bar and then click enter:

javascript:alert(document.title);

You can select and copy the text from the alert depending on the website and the web browser you are using.

To complement Jakub's answer, if you have access to the remote git server in ssh, you can go into the git remote directory and set:

user@remote$ git config receive.denyNonFastforwards false

Then go back to your local repo, try again to do your commit with --force:

user@local$ git push origin +master:master --force

And finally revert the server's setting in the original protected state:

user@remote$ git config receive.denyNonFastforwards true

Yes. The VBA equivalent of AltEnter is to use a linebreak character:

ActiveCell.Value = "I am a " & Chr(10) & "test"

Note that this automatically sets WrapText to True.

Proof:

Sub test()
Dim c As Range
Set c = ActiveCell
c.WrapText = False
MsgBox "Activcell WrapText is " & c.WrapText
c.Value = "I am a " & Chr(10) & "test"
MsgBox "Activcell WrapText is " & c.WrapText
End Sub

Use the open function to open the file. The open function returns a file object, which you can use the read and write to files:

file_input = open('input.txt') #opens a file in reading mode
file_output = open('output.txt') #opens a file in writing mode

data = file_input.read(1024) #read 1024 bytes from the input file
file_output.write(data) #write the data to the output file

I use my custom utility to cast an existing Collection if available.

Main:

public static <T> Collection<T> toCollection(Iterable<T> iterable) {
    if (iterable instanceof Collection) {
        return (Collection<T>) iterable;
    } else {
        return Lists.newArrayList(iterable);
    }
}

Ideally the above would use ImmutableList, but ImmutableCollection does not allow nulls which may provide undesirable results.

Tests:

@Test
public void testToCollectionAlreadyCollection() {
    ArrayList<String> list = Lists.newArrayList(FIRST, MIDDLE, LAST);
    assertSame("no need to change, just cast", list, toCollection(list));
}

@Test
public void testIterableToCollection() {
    final ArrayList<String> expected = Lists.newArrayList(FIRST, null, MIDDLE, LAST);

    Collection<String> collection = toCollection(new Iterable<String>() {
        @Override
        public Iterator<String> iterator() {
            return expected.iterator();
        }
    });
    assertNotSame("a new list must have been created", expected, collection);
    assertTrue(expected + " != " + collection, CollectionUtils.isEqualCollection(expected, collection));
}

I implement similar utilities for all subtypes of Collections (Set,List,etc). I'd think these would already be part of Guava, but I haven't found it.

You can specify GLOBIGNORE and use the pattern *

GLOBIGNORE='ignore1:ignore2' scp -r source/* remoteurl:remoteDir

You may wish to have general rules which you combine or override by using export GLOBIGNORE, but for ad-hoc usage simply the above will do. The : character is used as delimiter for multiple values.

theBoolean ^= true;

Fewer keystrokes if your variable is longer than four letters

Edit: code tends to return useful results when used as Google search terms. The code above doesn't. For those who need it, it's bitwise XOR as described here.

You can just use:

Date yourDate = new Date();

SimpleDateFormat DATE_FORMAT = new SimpleDateFormat("yyyy-MM-dd");
String date = DATE_FORMAT.format(yourDate);

It works perfectly!

CTRL+F5 Reloads the current page, ignoring cached content and generating the expected result.

INSTALL_FAILED_VERSION_DOWNGRADE

All Android apps have a package name. The package name uniquely identifies the app on the device. If same packageName as app that's already installed on the device then this error Showing .

1. You can uninstall the application from your device first and then install the fresh one .
2. You could simply increase the number by one each time a new version is released.

Since I reached two questions searching for my problem in a slightly different way, I am replicating my answer in case you end up here.

In the called function, you can define your type with:

emitWordCount(event: { target: HTMLInputElement }) {
  this.countUpdate.emit(event.target.value);
}

This assumes you are only interested in the target property, which is the most common case. If you need to access the other properties of event, a more comprehensive solution involves using the & type intersection operator:

event: Event & { target: HTMLInputElement }

You can also go more specific and instead of using HTMLInputElement you can use e.g. HTMLTextAreaElement for textareas.

You can validate group checkbox and radio button without extra js code, see below example.

Your JS should be look like:

$("#formid").validate();

You can play with HTML tag and attributes: eg. group checkbox [minlength=2 and maxlength=4]

<fieldset class="col-md-12">
  <legend>Days</legend>
  <div class="form-row">
    <div class="col-12 col-md-12 form-group">
        <label class="checkbox-inline">
          <input type="checkbox" name="daysgroup[]" value="1" required="required" data-msg-required="This value is required." minlength="2" maxlength="4" data-msg-maxlength="Max should be 4">Monday
        </label>
        <label class="checkbox-inline">
          <input type="checkbox" name="daysgroup[]" value="2">Tuesday
        </label>
        <label class="checkbox-inline">
          <input type="checkbox" name="daysgroup[]" value="3">Wednesday
        </label>
        <label class="checkbox-inline">
          <input type="checkbox" name="daysgroup[]" value="4">Thursday
        </label>
        <label class="checkbox-inline">
          <input type="checkbox" name="daysgroup[]" value="5">Friday
        </label>
        <label class="checkbox-inline">
          <input type="checkbox" name="daysgroup[]" value="6">Saturday
        </label>
        <label class="checkbox-inline">
          <input type="checkbox" name="daysgroup[]" value="7">Sunday
        </label>
        <label for="daysgroup[]" class="error">Your error message will be display here.</label>
    </div>
  </div>
</fieldset>

You can see here first or any one input should have required, minlength="2" and maxlength="4" attributes. minlength/maxlength as per your requirement.

eg. group radio button:

<fieldset class="col-md-12">
  <legend>Gender</legend>
  <div class="form-row">
    <div class="col-12 col-md-12 form-group">
        <label class="form-check-inline">
          <input type="radio" name="gendergroup[]" value="m" required="required" data-msg-required="This value is required.">man
        </label>
        <label class="form-check-inline">
          <input type="radio" name="gendergroup[]" value="w">woman
        </label>
        <label class="form-check-inline">
          <input type="radio" name="gendergroup[]" value="o">other
        </label>
        <label for="gendergroup[]" class="error">Your error message will be display here.</label>
    </div>
  </div>
</fieldset>

I solve this by using path variable. The sample code will look like below.

var path = require("path");

app.get('/', (req, res) => {
    res.sendFile(path.join(__dirname + '/index.html'));
})

While it was discussed in the comments, there isn't an answer containing it yet, so it can be easy to miss. DATE_FORMAT works really well and is flexible to handle many different patterns.

DATE_FORMAT(date,'%Y%m')

To put it in a query:

SELECT DATE_FORMAT(test_date,'%Y%m') AS date FROM test_table;

What I don't understand is what's the point of having a byte? Why not say 8 bits?

Apart from the technical point that a byte isn't necessarily 8 bits, the reasons for having a term is simple human nature:

• economy of effort (aka laziness) - it is easier to say "byte" rather than "eight bits"

• tribalism - groups of people like to use jargon / a private language to set them apart from others.

Just go with the flow. You are not going to change 50+ years of accumulated IT terminology and cultural baggage by complaining about it.

FWIW - the correct term to use when you mean "8 bits independent of the hardware architecture" is "octet".

Try this

$("[id*='type']").click(
function () {
var isCheckboxChecked = this.checked;
$("[id*='type']").attr('checked', false);
this.checked = isCheckboxChecked;
});

To make it even more generic you can also find checkboxes by the common class implemented on them.

In my case, the hard disk space upper bound was reached.

Look at this article: https://www.elastic.co/guide/en/elasticsearch/reference/current/disk-allocator.html

Basically, I ran:

PUT /_cluster/settings
{
  "transient": {
    "cluster.routing.allocation.disk.watermark.low": "90%",
    "cluster.routing.allocation.disk.watermark.high": "95%",
    "cluster.info.update.interval": "1m"
  }
}

So that it will allocate if <90% hard disk space used, and move a shard to another machine in the cluster if >95% hard disk space used; and it checks every 1 minute.

If you want to set 4 sides separately use:

border-width: 1px 2em 5px 0; /* top right bottom left */
border-style: solid dotted inset double;
border-color: #f00 #0f0 #00f #ff0;

Example using GPS latitude/longitude of 2 points.

var latitude1 = 39.46;
var longitude1 = -0.36;
var latitude2 = 40.40;
var longitude2 = -3.68;

var distance = google.maps.geometry.spherical.computeDistanceBetween(new google.maps.LatLng(latitude1, longitude1), new google.maps.LatLng(latitude2, longitude2));       

In React or any Javascript modules that internally use Webpack, if the src attribute value of img is given as a path in string format as given below

e.g. <img src={'/src/images/logo.png'} /> or <img src='/src/images/logo.png' />

then during build, the final HTML page built contains src='/src/images/logo.png'. This path is not read during build time, but is read during rendering in browser. At the rendering time, if the logo.png is not found in the /src/images directory, then the image would not render. If you open the console in browser, you can see the 404 error for the image. I believe you meant to use ./src directory instead of /src directory. In that case, the development directory ./src is not available to the browser. When the page is loaded in browser only the files in the 'public' directory are available to the browser. So, the relative path ./src is assumed to be public/src directory and if the logo.png is not found in public/src/images/ directory, it would not render the image.

So, the solution for this problem is either to put your image in the public directory and reference the relative path from public directory or use import or require keywords in React or any Javascript module to inform the Webpack to read this path during build phase and include the image in the final build output. The details of both these methods has been elaborated by Dan Abramov in his answer, please refer to it or use the link: https://create-react-app.dev/docs/adding-images-fonts-and-files/

var third = first.Except(second);

(you can also call ToList() after Except(), if you don't like referencing lazy collections.)

The Except() method compares the values using the default comparer, if the values being compared are of base data types, such as int, string, decimal etc.

Otherwise the comparison will be made by object address, which is probably not what you want... In that case, make your custom objects implement IComparable (or implement a custom IEqualityComparer and pass it to the Except() method).

I searched for a the same solution with a variable instead of the String.
I hope i can help someone with my solution :)

var numb = "3";
$(`#myid[data-tab-id=${numb}]`);

One may also use UNREFERENCED_PARAMETER defined in WinNT.H. The definition is just:

#define UNREFERENCED_PARAMETER(P)          (P)

And use it like:

void OnMessage(WPARAM wParam, LPARAM lParam)
{
    UNREFERENCED_PARAMETER(wParam);
    UNREFERENCED_PARAMETER(lParam);
}

Why would you use it, you might argue that you can just omit the variable name itself. Well, there are cases (different project configuration, Debug/Release builds) where the variable might actually be used. In another configuration that variable stands unused (and hence the warning).

Some static code analysis may still give warning for this non-nonsensical statement (wParam;). In that case, you mayuse DBG_UNREFERENCED_PARAMETER which is same as UNREFERENCED_PARAMETER in debug builds, and does P=P in release build.

#define DBG_UNREFERENCED_PARAMETER(P)      (P) = (P)

I am doing something like this to get mouse coordinates using Robot, I use these coordinates further in few of the games I am developing:

public class ForMouseOnly {
    public static void main(String[] args) throws InterruptedException {
        int x = MouseInfo.getPointerInfo().getLocation().x;
        int y = MouseInfo.getPointerInfo().getLocation().y;
        while (true) {

            if (x != MouseInfo.getPointerInfo().getLocation().x || y != MouseInfo.getPointerInfo().getLocation().y) {
                System.out.println("(" + MouseInfo.getPointerInfo().getLocation().x + ", "
                        + MouseInfo.getPointerInfo().getLocation().y + ")");
                x = MouseInfo.getPointerInfo().getLocation().x;
                y = MouseInfo.getPointerInfo().getLocation().y;
            }
        }
    }
}

This works for me on Java 6

    ServerSocket serverSocket = new ServerSocket(0);
    System.out.println("listening on port " + serverSocket.getLocalPort());

Here's what worked for me when restoring an exported database:

mongorestore -d 0 ./0 --drop

where ./contained the exported bson files. Note that the --drop will overwrite existing data.

I had a similar issue (using Jackson, lombok, gradle) and a POJO without no args constructor - the solution was to add

lombok.anyConstructor.addConstructorProperties=true

to the lombok.config file

Use the target attribute on your anchor tag with the _blank value.

Example:

<a href="http://google.com" target="_blank">Click Me!</a>

Ok so here's how I figured this out. It all has to do with CORS policy. Before the POST request, Chrome was doing a preflight OPTIONS request, which should be handled and acknowledged by the server prior to the actual request. Now this is really not what I wanted for such a simple server. Hence, resetting the headers client side prevents the preflight:

app.config(function ($httpProvider) {
  $httpProvider.defaults.headers.common = {};
  $httpProvider.defaults.headers.post = {};
  $httpProvider.defaults.headers.put = {};
  $httpProvider.defaults.headers.patch = {};
});

The browser will now send a POST directly. Hope this helps a lot of folks out there... My real problem was not understanding CORS enough.

Kudos to this answer for showing me the way.

I think you could create a separate css class that you can use in these cases:

.disable-transition {
  -webkit-transition: none;
  -moz-transition: none;
  -o-transition: color 0 ease-in;
  -ms-transition: none;
  transition: none;
}

Then in jQuery you would toggle the class like so:

$('#<your-element>').addClass('disable-transition');

For duplicating large files, xopy with /J switch is a good choice. In this case, simply pipe an F for file or a D for directory. Also, you can save jobs in an array for future references. For example:

$MyScriptBlock = {
    Param ($SOURCE, $DESTINATION) 
    'F' | XCOPY $SOURCE $DESTINATION /J/Y 
    #DESTINATION IS FILE, COPY WITHOUT PROMPT IN DIRECT BUFFER MODE
}
JOBS +=START-JOB -SCRIPTBLOCK $MyScriptBlock -ARGUMENTLIST $SOURCE,$DESTIBNATION
$JOBS | WAIT-JOB | REMOVE-JOB

Thanks to Chand with a bit modifications: https://stackoverflow.com/users/3705330/chand

This is an issue of selector specificity. (The selector .selected is less specific than ul.nav li.)

To fix, use as much specificity in the overriding rule as in the original:

ul.nav li {
 background-color:blue;
}
ul.nav li.selected {
 background-color:red;
}

You might also consider nixing the ul, unless there will be other .navs. So:

.nav li {
 background-color:blue;
}
.nav li.selected {
 background-color:red;
}

That's a bit cleaner, less typing, and fewer bits.

You can try next code:

function unique_randoms($min, $max, $count) {

 $arr = array();
 while(count($arr) < $count){
      $tmp =mt_rand($min,$max);
      if(!in_array($tmp, $arr)){
         $arr[] = $tmp;
      }
 }
return $arr;
}

I need to add stringsAsFactors=FALSE when creating the dataframe.

If it doesn't show up in your package manager (i.e. apt-cache search texinfo) and even apt-file search bin/makeinfo is no help, you may have to enable non-free/restricted packages for your package manager.

For ubuntu, sudo $EDITOR /etc/apt/sources.list and add restricted.

deb http://archive.ubuntu.com/ubuntu bionic main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu bionic-security main
deb http://archive.ubuntu.com/ubuntu bionic-updates main

For debian, sudo $EDITOR /etc/apt/sources.list and add non-free. You can even have preferences on package level if you don't want to clutter the package db with non-free stuff.

After a sudo apt-get udpate you should find the required package.

To complete some of the answers here, I had to get the ParametrizedType of MyGenericClass, no matter how high is the hierarchy, with the help of recursion:

private Class<T> getGenericTypeClass() {
        return (Class<T>) (getParametrizedType(getClass())).getActualTypeArguments()[0];
}

private static ParameterizedType getParametrizedType(Class clazz){
    if(clazz.getSuperclass().equals(MyGenericClass.class)){ // check that we are at the top of the hierarchy
        return (ParameterizedType) clazz.getGenericSuperclass();
    } else {
        return getParametrizedType(clazz.getSuperclass());
    }
}

You can do it using only the shell, no need for tr or sed

$ str="This is just a test"
$ echo ${str// /_}
This_is_just_a_test

I think I got what I was looking for..

data.train <- read.table("Assign2.WineComplete.csv",sep=",",header=T)
fit <- rpart(quality ~ ., method="class",data=data.train)
plot(fit)
text(fit, use.n=TRUE)
summary(fit)

instead of doing it like that, why not just make the flyout position:fixed, top:0; left:0; once your window has scrolled pass a certain height:

jQuery

  $(window).scroll(function(){
      if ($(this).scrollTop() > 135) {
          $('#task_flyout').addClass('fixed');
      } else {
          $('#task_flyout').removeClass('fixed');
      }
  });

css

.fixed {position:fixed; top:0; left:0;}

Example

In httpd.conf

1. Make sure these are loaded:

LoadModule headers_module modules/mod_headers.so

LoadModule rewrite_module modules/mod_rewrite.so

2. In the target directory:

<Directory "**/usr/local/PATH**">
    AllowOverride None
    Require all granted

    Header always set Access-Control-Allow-Origin "*"
    Header always set Access-Control-Allow-Methods "POST, GET, OPTIONS, DELETE, PUT"
    Header always set Access-Control-Allow-Headers "x-requested-with, Content-Type, origin, authorization, accept, client-security-token"
    Header always set Access-Control-Expose-Headers "Content-Security-Policy, Location"
    Header always set Access-Control-Max-Age "600"

    RewriteEngine On
    RewriteCond %{REQUEST_METHOD} OPTIONS
    RewriteRule ^(.*)$ $1 [R=200,L]

</Directory>

If running outside container, you may need to restart apache service.

Try lodash sortBy

import * as _ from "lodash";
_.sortBy(data.applications,"id").map(application => (
    console.log("application")
    )
)

Read more : lodash.sortBy

add this to your package.json file

scripts {
"dev": "nodemon --watch '**/*.ts' --exec 'ts-node' index.ts"
}

and to make this work you also need to install ts-node as dev-dependency

yarn add ts-node -D

run yarn dev to start the dev server

I figured out that this behaves like a mousedown event:

button:active:hover {}

Here you can read more about different HTML parsers in Python and their performance. Even though the article is a bit dated it still gives you a good overview.

Python HTML parser performance

I'd recommend BeautifulSoup even though it isn't built in. Just because it's so easy to work with for those kinds of tasks. Eg:

import urllib2
from BeautifulSoup import BeautifulSoup

page = urllib2.urlopen('http://www.google.com/')
soup = BeautifulSoup(page)

x = soup.body.find('div', attrs={'class' : 'container'}).text

The jQuery you're using is manipulates the DOM, not the CSS itself. Try changing the word span in your CSS to .mySpan, then apply that class to one or more DOM elements in your HTML like so:

...
<span class="mySpan">...</span>
...

Then, change your jQuery as follows:

$(".mySpan").css({ display : inline });

This should work much better.

Good luck!

Yes;

git commit FILE

will commit just FILE. Then you can use

git reset --hard

to undo local changes in other files.

There may be other ways too that I don't know about...

edit: or, as NicDumZ said, git-checkout just the files you want to undo the changes on (the best solution depends on wether there are more files to commit or more files to undo :-)

I suggest

l = re.compile("(?<!^)\s+(?=[A-Z])(?!.\s)").split(s)

Check this demo.

Python can do unexpected things when new objects are defined from existing ones. You stated in a comment above that your dataframe is defined along the lines of df = df_all.loc[df_all['issueid']==specific_id,:]. In this case, df is really just a stand-in for the rows stored in the df_all object: a new object is NOT created in memory.

To avoid these issues altogether, I often have to remind myself to use the copy module, which explicitly forces objects to be copied in memory so that methods called on the new objects are not applied to the source object. I had the same problem as you, and avoided it using the deepcopy function.

In your case, this should get rid of the warning message:

from copy import deepcopy
df = deepcopy(df_all.loc[df_all['issueid']==specific_id,:])
df['industry'] = 'yyy'

EDIT: Also see David M.'s excellent comment below!

df = df_all.loc[df_all['issueid']==specific_id,:].copy()
df['industry'] = 'yyy'

For anybody else looking, here is a decent set of steps. http://forums.asp.net/t/1678976.aspx/1

Don't forget to manually add your key in OnActionExecuting() like I did.

If you would like a slightly more targeted approach than the blanket chown -R, you may find this fix-homebrew script useful:

#!/bin/sh

[ -e `which brew` ] || {
    echo Homebrew doesn\'t appear to be installed.
    exit -1
}

BREW_ROOT="`dirname $(dirname $(which brew))`"
BREW_GROUP=admin
BREW_DIRS=".git bin sbin Library Cellar share etc lib opt CONTRIBUTING.md README.md SUPPORTERS.md"

echo "This script will recursively update the group on the following paths"
echo "to the '${BREW_GROUP}' group and make them group writable:"
echo ""

for dir in $BREW_DIRS ; do {
    [ -e "$BREW_ROOT/$dir" ] && echo "    $BREW_ROOT/$dir "
} ; done

echo ""
echo "It will also stash (and clean) any changes that are currently in the homebrew repo, so that you have a fresh blank-slate."
echo ""

read -p 'Press any key to continue or CTRL-C to abort.'

echo "You may be asked below for your login password."
echo ""

# Non-recursively update the root brew path.
echo Updating "$BREW_ROOT" . . .
sudo chgrp "$BREW_GROUP" "$BREW_ROOT"
sudo chmod g+w "$BREW_ROOT"

# Recursively update the other paths.
for dir in $BREW_DIRS ; do {
    [ -e "$BREW_ROOT/$dir" ] && (
        echo Recursively updating "$BREW_ROOT/$dir" . . .
        sudo chmod -R g+w "$BREW_ROOT/$dir"
        sudo chgrp -R "$BREW_GROUP" "$BREW_ROOT/$dir"
    )
} ; done

# Non-distructively move any git crud out of the way
echo Stashing changes in "$BREW_ROOT" . . .
cd $BREW_ROOT
git add .
git stash
git clean -d -f Library

echo Finished.

Instead of doing a chmod to your user, it gives the admin group (to which you presumably belong) write access to the specific directories in /usr/local that homebrew uses. It also tells you exactly what it intends to do before doing it.

Another base R solution would be to split the data frame per cat, after that using lapply: add a column with number 1:nrow(x). The last step is to have your final data frame back with do.call, that is:

        df_split <- split(df, df$cat)
        df_lapply <- lapply(df_split, function(x) {
          x$num <- seq_len(nrow(x))
          return(x)
        })
        df <- do.call(rbind, df_lapply)

To overcome the issue of Win7 32bit VB6, try copying from Windows Server 2003 C:\Windows\system32\ the files mscomctl.ocx and mscomcctl.oba.

When nginx returns 400(bad request) it will log the reason into error log, at "info" level and take a look into error log when testing.

You are trying to access the struct statically with a . instead of ::, nor are its members static. Either instantiate ReducedForm:

ReducedForm rf;
rf.iSimplifiedNumerator = 5;

or change the members to static like this:

struct ReducedForm
{
    static int iSimplifiedNumerator;
    static int iSimplifiedDenominator;
};

In the latter case, you must access the members with :: instead of . I highly doubt however that the latter is what you are going for ;)

I created a form data object and appended the file:

var form = new FormData(); 
form.append("video", $("#fileInput")[0].files[0]);

and i got:

------WebKitFormBoundaryNczYRonipfsmaBOK
Content-Disposition: form-data; name="video"; filename="Wildlife.wmv"
Content-Type: video/x-ms-wmv

in the headers sent. I can confirm this works because my file was sent and stored in a folder on my server. If you don't know how to use the FormData object there is some documentation online, but not much. Form Data Object Explination by Mozilla

I don't know ASP.NET very well, but can you use the ternary operator?

http://en.wikipedia.org/wiki/Ternary_operation

Something like: (x=Eval("item")) == Null ? 0 : x

After attempting a few of these solutions and not having any success, this is what worked for me:

1. Restart system

3. Success!

You can use tee to write the result of your query to a file:

tee somepath\filename.txt

[Daemon process]

Java uses user thread and daemon tread concepts.

JVM flow

1. If there are no `user treads` JVM starts terminating the program
2. JVM terminates all `daemon threads` automatically without waiting when they are done
3. JVM is shutdown

As you see daemon tread is a service thread for user treads.

• daemon tread is low priority thread.
• Thread inherits it's properties from parent thread. To set it externally you can use setDaemon() method before starting it or check it via isDaemon()

from flask import Flask, render_template, make_response
app = Flask(__name__)

@app.route('/user/xml')
def user_xml():
    resp = make_response(render_template('xml/user.html', username='Ryan'))
    resp.headers['Content-type'] = 'text/xml; charset=utf-8'
    return resp

This seems to work okay for me. yourDateTime.ToString().Substring(2);

I think you might want:

String encodedFile = Base64.getEncoder().encodeToString(bytes);

The & and | are usually bitwise operations.

Where as && and || are usually logical operations.

For comparison purposes, it's perfectly fine provided that everything returns either a 1 or a 0. Otherwise, it can return false positives. You should avoid this though to prevent hard to read bugs.

I had the same issue with different circumstances.
I had simple element inside the body tag.
The solution was:

<asp:PlaceHolder ID="container" runat="server">
    <a id="child" href="<%# variable %>">Change me</a>
</asp:PlaceHolder>

protected new void Page_Load(object sender, EventArgs e)
{    
    Page.Form.DataBind(); // I neded to Call DataBind on Form not on Header
    container.InnerHtml = "Simple text";
}

Use the start and end delimiters: ^abc$

Add the folders which you don't want to trigger servlet processing to the <static-files> section of your appengine-web.xml file.

I just did this and looks like things are starting to work ok. Here's my structure:

/

/pages/<.jsp files>

/css

I added "/pages/**" and "/css/**" to the <static-files> section and I can now forward to a .jsp file from inside a servlet doGet without causing an infinite loop.

You can use angular's $window object:

$window.onload = function(e) {
  //your magic here
}

import subprocess
result = []
win_cmd = 'ipconfig'(curr_user,filename,ip_address)
process = subprocess.Popen(win_cmd,
shell=True,
stdout=subprocess.PIPE,
stderr=subprocess.PIPE )
for line in process.stdout:
    print line
result.append(line)
errcode = process.returncode
for line in result:
    print line

(This is for the benefit of others who may refer)

You can simply use cin and a char array. The cin input is delimited by the first whitespace it encounters.

#include<iostream>
using namespace std;

main()
{
    char word[50];
    cin>>word;
    while(word){
        //Do stuff with word[]
        cin>>word;
    }
}

Use the instanceof syntax.

Like so:

Object foo = "";

if( foo instanceof String ) {
  // do something String related to foo
}

Are you creating a very large table (hundreds of rows and columns)? If so, table-layout: fixed; is a good idea, as the browser only needs to read the first row in order to compute and render the entire table, so it loads faster.

But if not, I would suggest dumping table-layout: fixed; and changing your css as follows:

table th, table td{
border: 1px solid #000;
width:20px;  //or something similar   
}

table td.wideRow, table th.wideRow{
width: 300px;
}

http://jsfiddle.net/6p9K3/1/

function isEmpty(val) {
if(val.length ==0 || val.length ==null){
    return 'emptyForm';
}else{
    return 'not emptyForm';
}

}

$(document).ready(function(){enter code here
    $( "form" ).submit(function( event ) {
        $('input').each(function(){
           var getInputVal = $(this).val();
            if(isEmpty(getInputVal) =='emptyForm'){
                alert(isEmpty(getInputVal));
            }else{
                alert(isEmpty(getInputVal));
            }
        });
        event.preventDefault();
    });
});

If one wants to support Generics (in an extension method) this is the pattern...

public  static List<T> Deserialize<T>(this string SerializedJSONString)
{
    var stuff = JsonConvert.DeserializeObject<List<T>>(SerializedJSONString);
    return stuff;
}

It is used like this:

var rc = new MyHttpClient(URL);
//This response is the JSON Array (see posts above)
var response = rc.SendRequest();
var data = response.Deserialize<MyClassType>();

MyClassType looks like this (must match name value pairs of JSON array)

[JsonObject(MemberSerialization = MemberSerialization.OptIn)]
 public class MyClassType
 {
    [JsonProperty(PropertyName = "Id")]
    public string Id { get; set; }

    [JsonProperty(PropertyName = "Name")]
    public string Name { get; set; }

    [JsonProperty(PropertyName = "Description")]
    public string Description { get; set; }

    [JsonProperty(PropertyName = "Manager")]
    public string Manager { get; set; }

    [JsonProperty(PropertyName = "LastUpdate")]
    public DateTime LastUpdate { get; set; }
 }

Use NUGET to download Newtonsoft.Json add a reference where needed...

using Newtonsoft.Json;

It looks like you just want:

eventCustom.DateTimeEnd = string.IsNullOrWhiteSpace(dateTimeEnd)
    ? (DateTime?) null
    : DateTime.Parse(dateTimeEnd);

Note that this will throw an exception if dateTimeEnd isn't a valid date.

An alternative would be:

DateTime validValue;
eventCustom.DateTimeEnd = DateTime.TryParse(dateTimeEnd, out validValue)
    ? validValue
    : (DateTime?) null;

That will now set the result to null if dateTimeEnd isn't valid. Note that TryParse handles null as an input with no problems.

In your js/ts file for the html that will be hovered

@Output() elemHovered: EventEmitter<any> = new EventEmitter<any>();
onHoverEnter(): void {
    this.elemHovered.emit([`The button was entered!`,this.event]);
}

onHoverLeave(): void {
    this.elemHovered.emit([`The button was left!`,this.event])
}

In your HTML that will be hovered

 (mouseenter) = "onHoverEnter()" (mouseleave)="onHoverLeave()"

In your js/ts file that will receive info of the hovering

elemHoveredCatch(d): void {
    console.log(d)
}

In your HTML element that is connected with catching js/ts file

(elemHovered) = "elemHoveredCatch($event)"

Not for this Problem, but here's some code to compare lists for equal and not! identical objects:

public class EquatableList<T> : List<T>, IEquatable<EquatableList<T>> where    T : IEquatable<T>

/// <summary>
/// True, if this contains element with equal property-values
/// </summary>
/// <param name="element">element of Type T</param>
/// <returns>True, if this contains element</returns>
public new Boolean Contains(T element)
{
    return this.Any(t => t.Equals(element));
}

/// <summary>
/// True, if list is equal to this
/// </summary>
/// <param name="list">list</param>
/// <returns>True, if instance equals list</returns>
public Boolean Equals(EquatableList<T> list)
{
    if (list == null) return false;
    return this.All(list.Contains) && list.All(this.Contains);
}

The reference to 480px has been removed. Instead it says:

/* Extra small devices (phones, less than 768px) */
/* No media query since this is the default in Bootstrap */

There isn't a breakpoint below 768px in Bootstrap 3.

If you want to use the @screen-sm-min and other mixins then you need to be compiling with LESS, see http://getbootstrap.com/css/#grid-less

Here's a tutorial on how to use Bootstrap 3 and LESS: http://www.helloerik.com/bootstrap-3-less-workflow-tutorial

You're trying to use k (which is a list) as a key for d. Lists are mutable and can't be used as dict keys.

Also, you're never initializing the lists in the dictionary, because of this line:

if k not in d == False:

Which should be:

if k not in d == True:

Which should actually be:

if k not in d:

Another way to find out where a class is loaded from (without manipulating the source) is to start the Java VM with the option: -verbose:class

This gives you the needed results:

string time = "16:23:01";
var result = Convert.ToDateTime(time);
string test = result.ToString("hh:mm:ss tt", CultureInfo.CurrentCulture);
//This gives you "04:23:01 PM"  string

You could also use CultureInfo.CreateSpecificCulture("en-US") as not all cultures will display AM/PM.

This might sound strange but you can remove next line by copying the whole text and pasting it in firefox search bar, and then re-pasting it in notepad++

The problem is that you're (probably) trying to plot a vector that consists exclusively of missing (NA) values. Here's an example:

> x=rep(NA,100)
> y=rnorm(100)
> plot(x,y)
Error in plot.window(...) : need finite 'xlim' values
In addition: Warning messages:
1: In min(x) : no non-missing arguments to min; returning Inf
2: In max(x) : no non-missing arguments to max; returning -Inf

In your example this means that in your line plot(costs,pseudor2,type="l"), costs is completely NA. You have to figure out why this is, but that's the explanation of your error.

From comments:

Scott C Wilson: Another possible cause of this message (not in this case, but in others) is attempting to use character values as X or Y data. You can use the class function to check your x and Y values to be sure if you think this might be your issue.

stevec: Here is a quick and easy solution to that problem (basically wrap x in as.factor(x))

No.. It is not proper way. Refer the steps,

For Classpath reference: Right click on project in Eclipse -> Buildpath -> Configure Build path -> Java Build Path (left Pane) -> Libraries(Tab) -> Add External Jars -> Select your jar and select OK.

For Deployment Assembly: Right click on WAR in eclipse-> Buildpath -> Configure Build path -> Deployment Assembly (left Pane) -> Add -> External file system -> Add -> Select your jar -> Add -> Finish.

This is the proper way! Don't forget to remove environment variable. It is not required now.

Try this. Surely it will work. Try to use Maven, it will simplify you task.

The code you posted gives the critical value for a one-sided test (Hence the answer to you question is simply:

abs(qt(0.25, 40)) # 75% confidence, 1 sided (same as qt(0.75, 40))
abs(qt(0.01, 40)) # 99% confidence, 1 sided (same as qt(0.99, 40))

Note that the t-distribution is symmetric. For a 2-sided test (say with 99% confidence) you can use the critical value

abs(qt(0.01/2, 40)) # 99% confidence, 2 sided

You can follow one of the below approaches:

1) Basic, single type :

//One type
public static <T> void fill(List <T> list, T val) {

    for(int i=0; i<list.size(); i++){
        list.set(i, val);
    }

}

2) Multiple Types :

// multiple types as parameters
public static <T1, T2> String multipleTypeArgument(T1 val1, T2 val2) {

    return val1+" "+val2;

}

3) Below will raise compiler error as 'T3 is not in the listing of generic types that are used in function declaration part.

//Raised compilation error
public static <T1, T2> T3 returnTypeGeneric(T1 val1, T2 val2) {
    return 0;
}

Correct : Compiles fine

public static <T1, T2, T3> T3 returnTypeGeneric(T1 val1, T2 val2) {
    return 0;
}

Sample Class Code :

package generics.basics;

import java.util.ArrayList;
import java.util.List;

public class GenericMethods {

/*
 Declare the generic type parameter T in this method. 

 After the qualifiers public and static, you put <T> and 
 then followed it by return type, method name, and its parameters.

 Observe : type of val is 'T' and not '<T>'

 * */

The CSS solutions don't appear to be widely available as of mid-2013. Instead...

1. Nicholas Zakas explains that Modernizr applies a no-touch CSS class when the browser doesn’t support touch.

2. Or detect in JavaScript with a simple piece of code, allowing you to implement your own Modernizr-like solution:

   <script>
       document.documentElement.className += 
       (("ontouchstart" in document.documentElement) ? ' touch' : ' no-touch');
   </script>
   

   Then you can write your CSS as:

   .no-touch .myClass {
       ...
   }
   .touch .myClass {
       ...
   }
   

It's important to note that the order of parameters is actually important to spring. The BindingResult needs to come right after the Form that is being validated. Likewise, the [optional] Model parameter needs to come after the BindingResult. Example:

Valid:

@RequestMapping(value = "/entry/updateQuantity", method = RequestMethod.POST)
public String updateEntryQuantity(@Valid final UpdateQuantityForm form,
                                  final BindingResult bindingResult,
                                  @RequestParam("pk") final long pk,
                                  final Model model) {
}

Not Valid:

RequestMapping(value = "/entry/updateQuantity", method = RequestMethod.POST)
public String updateEntryQuantity(@Valid final UpdateQuantityForm form,
                                  @RequestParam("pk") final long pk,
                                  final BindingResult bindingResult,
                                  final Model model) {
}

You can't have a switch in render. The psuedo-switch approach of placing an object-literal that accesses one element isn't ideal because it causes all views to process and that can result in dependency errors of props that don't exist in that state.

Here's a nice clean way to do it that doesn't require each view to render in advance:

render () {
  const viewState = this.getViewState();

  return (
    <div>
      {viewState === ViewState.NO_RESULTS && this.renderNoResults()}
      {viewState === ViewState.LIST_RESULTS && this.renderResults()}
      {viewState === ViewState.SUCCESS_DONE && this.renderCompleted()}
    </div>
  )

If your conditions for which view state are based on more than a simple property – like multiple conditions per line, then an enum and a getViewState function to encapsulate the conditions is a nice way to separate this conditional logic and cleanup your render.

in your server.py file make : host ='192.168.1.94' instead of host = socket.gethostname()

This is a common function of Adorners in WPF. Adorners typically appear above all other controls, but the other answers that mention z-order may fit your case better.

For me, I just had to go into the Job Activity Monitor and stop two things that were processing. Then it went offline immediately. In my case though I knew what those 2 processes were and that it was ok to stop them.

The difference between a tuple and a class is that a tuple has no property names. This is almost never a good thing, and I would only use a tuple when the arguments are fairly meaningless like in an abstract math formula Eg. abstract calculus over 5,6,7 dimensions might take a tuple for the coordinates.

for future use find day of the week ,deduct day and display the deducted day using date.

public static void main(String args[]) throws ParseException {

String[] days = { "Sunday", "Monday", "Tuesday", "Wednesday",
        "Thursday", "Friday", "Saturday" };
SimpleDateFormat format1 = new SimpleDateFormat("dd/MM/yyyy");
Date dt1 = format1.parse("20/10/2013");

Calendar c = Calendar.getInstance();
c.setTime(dt1);
int dayOfWeek = c.get(Calendar.DAY_OF_WEEK);
long diff = Calendar.getInstance().getTime().getTime() ;
System.out.println(dayOfWeek);

switch (dayOfWeek) {

case 6:
    System.out.println(days[dayOfWeek - 1]);
    break;
case 5:

    System.out.println(days[dayOfWeek - 1]);
    break;      
case 4:
    System.out.println(days[dayOfWeek - 1]);
    break;
case 3:

    System.out.println(days[dayOfWeek - 1]);
    break;
case 2:
    System.out.println(days[dayOfWeek - 1]);
    break;
case 1:

    System.out.println(days[dayOfWeek - 1]);

     diff = diff -(dt1.getTime()- 3 );
     long valuebefore = dt1.getTime();
     long valueafetr = dt1.getTime()-2;
     System.out.println("DATE IS befor subtraction :"+valuebefore);
     System.out.println("DATE IS after subtraction :"+valueafetr);

     long x= dt1.getTime()-(2 * 24 * 3600 * 1000);
     System.out.println("Deducted date to find firday is - 2 days form Sunday :"+new Date((dt1.getTime()-(2*24*3600*1000))));
     System.out.println("DIffrence from now on is :"+diff);
        if(diff > 0) {

            diff = diff / (1000 * 60 * 60 * 24);
            System.out.println("Diff"+diff);
            System.out.println("Date is Expired!"+(dt1.getTime() -(long)2));
        }

    break;
}
}

For this the System.Timers.Timer works best

// Create a timer
myTimer = new System.Timers.Timer();
// Tell the timer what to do when it elapses
myTimer.Elapsed += new ElapsedEventHandler(myEvent);
// Set it to go off every five seconds
myTimer.Interval = 5000;
// And start it        
myTimer.Enabled = true;

// Implement a call with the right signature for events going off
private void myEvent(object source, ElapsedEventArgs e) { }

See Timer Class (.NET 4.6 and 4.5) for details

A completely alternative solution is to not use the MVC HandleErrorAttribute, and instead rely on ASP.Net error handling, which Elmah is designed to work with.

You need to remove the default global HandleErrorAttribute from App_Start\FilterConfig (or Global.asax), and then set up an error page in your Web.config:

<customErrors mode="RemoteOnly" defaultRedirect="~/error/" />

Note, this can be an MVC routed URL, so the above would redirect to the ErrorController.Index action when an error occurs.

1) Update to Python 3.6.5 using the native app installer downloaded from the official Python language website https://www.python.org/downloads/

I've found that the installer is taking care of updating the links and symlinks for the new Python a lot better than homebrew.

2) Install a new certificate using "./Install Certificates.command" which is in the refreshed Python 3.6 directory

> cd "/Applications/Python 3.6/"
> sudo "./Install Certificates.command"

los.Aggregate((current, next) => current + "," + next);

This works in Chrome, Firefox, doesn't work in Safari :(, haven't tested in other browsers

If you don't care about preserving the factors, and want to apply it to any column that can get converted to numeric, I used the script below. if df is your original dataframe, you can use the script below.

df[] <- lapply(df, as.character)
df <- data.frame(lapply(df, function(x) ifelse(!is.na(as.numeric(x)), as.numeric(x),  x)))

John Gordon's answer was the first of dozens of half-explained / documented answers I tried, from many, many sites, that actually worked. Thank You Mr Gordon. Sorry I don't have the points to up-tick your answer.

I would like to add, for other newbies to node-route-file-splitting, that the use of the anonymous function for 'index' is what one will more often see, so using John's example for the main.js, the functionally-equivalent code one would normally find is:

app.get('/',(req, res) {
    res.render('index', { title: 'Express' });
});

Easy way in kotlin

In your fragment

requireActivity().window.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE or WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN)

In your layout :

android:fitsSystemWindows="true"

The VPATH option might come in handy, which tells make what directories to look in for source code. You'd still need a -I option for each include path, though. An example:

CXXFLAGS=-Ipart1/inc -Ipart2/inc -Ipart3/inc
VPATH=part1/src:part2/src:part3/src

OutputExecutable: part1api.o part2api.o part3api.o

This will automatically find the matching partXapi.cpp files in any of the VPATH specified directories and compile them. However, this is more useful when your src directory is broken into subdirectories. For what you describe, as others have said, you are probably better off with a makefile for each part, especially if each part can stand alone.

May I just leave it here

s = 'foo/bar spam\neggs'
print(s.replace('/', '+++/+++').replace(' ', '+++ +++').replace('\n', '+++\n+++').split('+++'))

['foo', '/', 'bar', ' ', 'spam', '\n', 'eggs']

This is the logger class that I use. The private Log() method has EventLog.WriteEntry() in it, which is how you actually write to the event log. I'm including all of this code here because it's handy. In addition to logging, this class will also make sure the message isn't too long to write to the event log (it will truncate the message). If the message was too long, you'd get an exception. The caller can also specify the source. If the caller doesn't, this class will get the source. Hope it helps.

By the way, you can get an ObjectDumper from the web. I didn't want to post all that here. I got mine from here: C:\Program Files (x86)\Microsoft Visual Studio 10.0\Samples\1033\CSharpSamples.zip\LinqSamples\ObjectDumper

I don't know how we all missed this: localizedStringFromDate:dateStyle:timeStyle:

NSString *dateString = [NSDateFormatter localizedStringFromDate:[NSDate date]

NSLog(@"%@",dateString);

outputs '13/06/12 00:22:39 GMT+03:00'

You need to assign some height to make the overflow: auto; property work.
For testing purpose, add height: 100px; and check.
and also it will be better if you give overflow-y:auto; instead of overflow: auto;, because this makes the element to scroll only vertical but not horizontal.

float:left;
width:1000px;
overflow-y: auto;
height: 100px;

If you don't know the height of the container and you want to show vertical scrollbar when the container reaches a fixed height say 100px, use max-height instead of height property.

SparkSQl support writing programs using Dataset and Dataframe API, along with it need to support sql.

In order to support Sql on DataFrames, first it requires a table definition with column names are required, along with if it creates tables the hive metastore will get lot unnecessary tables, because Spark-Sql natively resides on hive. So it will create a temporary view, which temporarily available in hive for time being and used as any other hive table, once the Spark Context stop it will be removed.

In order to create the view, developer need an utility called createOrReplaceTempView

After you get from Eclipse the ugly CheckoutConflictException, the Eclipse-Merge Tool button is disabled.

Git need alle your files added to the Index for enable Merging.

So, to merge your Changes and commit them you need to add your files first to the index "Add to Index" and "Commit" them without "Push". Then you should see one pending pull and one pending push request in Eclipse. You see that in one up arrow and one down arrow.

If all conflict Files are in the commit, you can "pull" again. Then you will see something like:

\< < < < < < < HEAD Server Version \======= Local Version > > > > > > > branch 'master' of ....git

Then you either change it by the Merge-Tool, which is now enable or just do the merge by hand direct in the file. In the last step, you have to add the modified files again to the index and "Commit and Push" them.

Checking done!

I have few suggession for the above mentioned error.

? Check executor memory assigned as an executor might have to deal with partitions requiring more memory than what is assigned.

? Try to see if more shuffles are live as shuffles are expensive operations since they involve disk I/O, data serialization, and network I/O

? Use Broadcast Joins

? Avoid using groupByKeys and try to replace with ReduceByKey

? Avoid using huge Java Objects wherever shuffling happens

Use this code instead of it:

$users = Users::all()->unique('name');

From the @param wiki page:

Parameters With Properties

If a parameter is expected to have a particular property, you can document that immediately after the @param tag for that parameter, like so:

 /**
  * @param userInfo Information about the user.
  * @param userInfo.name The name of the user.
  * @param userInfo.email The email of the user.
  */
 function logIn(userInfo) {
        doLogIn(userInfo.name, userInfo.email);
 }

There used to be a @config tag which immediately followed the corresponding @param, but it appears to have been deprecated (example here).

IMO, in your case you can try this:

1. Map the shared folder to a drive or folder on your machine. (here's how)
2. Access the mapped drive/folder as you normally would local files.

Nothing needs to be installed. No services need to be running except those that enable folder sharing.

If you can access the shared folder and maps it on your machine, most things should work just like local files, including command prompts and all explorer-enhancement tools.

This is different from using PsExec (or RDP-ing in) in that you do not need to have administrative rights and/or remote desktop/terminal services connection rights on the remote server, you just need to be able to access those shared folders.

Also make sure you have all the necessary security permissions to run whatever commands/tools you want to run on those shared folders as well.

If, however you wish the processing to be done on the target machine, then you can try PsExec as @divo and @recursive pointed out, something alongs:

PsExec \\yourServerName -u yourUserName cmd.exe

Which will brings gives you a command prompt at the remote machine. And from there you can execute whatever you want.

I am not sure but I think you need either the Server (lanmanserver) or the Terminal Services (TermService) service to be running (which should have already be running).

This error can be caused by the permissions to the file, which you should check, however recently I noticed that the same is thrown if the file has been transferred and windows has marked the file as 'Encrypt Contents to Secure Data'.

You can find this by bringing up the .bak file properties and clicking the advanced button, it appears as the last check box on the dialog.

Hope that helps someone!

This solution worked perfectly for me

var table = document.getElementById("myTable").rows;
var y;
for(i = 0; i < # of rows; i++)
{    for(j = 0; j < # of columns; j++)
     {
         y = table[i].cells;
         //do something with cells in a row
         y[j].innerHTML = "";
     }
}

Use array_shift function

$myarray = array_shift($myarray);

This will move array elements one level up and you can access any array element without using [0] key

echo $myarray['email'];  

will show [email protected]

We can have two ways of calling the functions written in pgadmin for postgre sql database.

Suppose we have defined the function as below:

CREATE OR REPLACE FUNCTION helloWorld(name text) RETURNS void AS $helloWorld$
DECLARE
BEGIN
    RAISE LOG 'Hello, %', name;
END;
$helloWorld$ LANGUAGE plpgsql;

We can call the function helloworld in one of the following way:

SELECT "helloworld"('myname');

SELECT public.helloworld('myname')

In Eclipse:

• goto run menu -> run configuration.
• right click on android application on the right side and click new.
• fill the corresponding details like project name under the android tab.
• then under the target tab.
• select 'launch on all compatible devices and then select active devices from the drop down list'.
• save the configuration and run it by either clicking run on the 'run' button on the bottom right side of the window or close the window and run again

Because array access is defined in terms of pointers. a[i] is defined to mean *(a + i), which is commutative.

You can even give multiple columns with null values and get multiple quantile values (I use 95 percentile for outlier treatment)

my_df[['field_A','field_B']].dropna().quantile([0.0, .5, .90, .95])

By default, postgres tries to connect to a database with the same name as your user. To prevent this default behaviour, just specify user and database:

psql -U Username DatabaseName 

if you want to use it in all of your classes you can use:

public var yourVariable = "something"

if you want to use just in one class you can use :

var yourVariable = "something"

Command go

Download and install packages and dependencies

Usage:

go get [-d] [-f] [-t] [-u] [-v] [-fix] [-insecure] [build flags] [packages]

Get downloads the packages named by the import paths, along with their dependencies. It then installs the named packages, like 'go install'.

The -d flag instructs get to stop after downloading the packages; that is, it instructs get not to install the packages.

The -f flag, valid only when -u is set, forces get -u not to verify that each package has been checked out from the source control repository implied by its import path. This can be useful if the source is a local fork of the original.

The -fix flag instructs get to run the fix tool on the downloaded packages before resolving dependencies or building the code.

The -insecure flag permits fetching from repositories and resolving custom domains using insecure schemes such as HTTP. Use with caution.

The -t flag instructs get to also download the packages required to build the tests for the specified packages.

The -u flag instructs get to use the network to update the named packages and their dependencies. By default, get uses the network to check out missing packages but does not use it to look for updates to existing packages.

The -v flag enables verbose progress and debug output.

Get also accepts build flags to control the installation. See 'go help build'.

When checking out a new package, get creates the target directory GOPATH/src/. If the GOPATH contains multiple entries, get uses the first one. For more details see: 'go help gopath'.

When checking out or updating a package, get looks for a branch or tag that matches the locally installed version of Go. The most important rule is that if the local installation is running version "go1", get searches for a branch or tag named "go1". If no such version exists it retrieves the default branch of the package.

When go get checks out or updates a Git repository, it also updates any git submodules referenced by the repository.

Get never checks out or updates code stored in vendor directories.

For more about specifying packages, see 'go help packages'.

For more about how 'go get' finds source code to download, see 'go help importpath'.

This text describes the behavior of get when using GOPATH to manage source code and dependencies. If instead the go command is running in module-aware mode, the details of get's flags and effects change, as does 'go help get'. See 'go help modules' and 'go help module-get'.

See also: go build, go install, go clean.

For example, showing verbose output,

$ go get -v github.com/capotej/groupcache-db-experiment/...
github.com/capotej/groupcache-db-experiment (download)
github.com/golang/groupcache (download)
github.com/golang/protobuf (download)

$ 

Usually you make the thing you don't want duplicates of unique, and allow the database itself to refuse the insert.

Otherwise, you can use INSERT INTO, see How to avoid duplicates in INSERT INTO SELECT query in SQL Server?

This is what I did:

$ wget http://sourceforge.net/projects/mcrypt/files/Libmcrypt/2.5.8/libmcrypt-2.5.8.tar.gz/download
$ tar xzvf libmcrypt-2.5.8.tar.gz
$ ./configure
$ make
$ sudo make install

$ brew install autoconf

$ wget file:///Users/rmatikolai/Downloads/php-5.4.24.tar.bz2
$ tar xjvf php-5.4.24.tar.bz2
$ cd php-5.4.24/ext/mcrypt
$ phpize
$ ./configure # this is the step which fails without the above dependencies
$ make
$ make test
$ sudo make install


$ sudo cp /private/etc/php.ini.default /private/etc/php.ini
$ sudo vi /private/etc/php.ini

Next, you need to add the line:

extension=mcrypt.so

$ sudo apachectl restart

You can just use np.savetxt and access the np attribute .values:

np.savetxt(r'c:\data\np.txt', df.values, fmt='%d')

yields:

18 55 1 70
18 55 2 67
18 57 2 75
18 58 1 35
19 54 2 70

or to_csv:

df.to_csv(r'c:\data\pandas.txt', header=None, index=None, sep=' ', mode='a')

Note for np.savetxt you'd have to pass a filehandle that has been created with append mode.

You said :

Maybe my data.frame is not in a good format?

Yes this is true. Your data is in the wide format You need to put it in the long format. Generally speaking, long format is better for variables comparison.

Using reshape2 for example , you do this using melt:

dat.m <- melt(dat,id.vars = "Rank") ## just melt(dat) should work

Then you get your barplot:

ggplot(dat.m, aes(x = Rank, y = value,fill=variable)) +
    geom_bar(stat='identity')

But using lattice and barchart smart formula notation , you don't need to reshape your data , just do this:

barchart(F1+F2+F3~Rank,data=dat)

Possibly the fastest solution is to operate in plain Python:

Series(
    map(
        '_'.join,
        df.values.tolist()
        # when non-string columns are present:
        # df.values.astype(str).tolist()
    ),
    index=df.index
)

Comparison against @MaxU answer (using the big data frame which has both numeric and string columns):

%timeit big['bar'].astype(str) + '_' + big['foo'] + '_' + big['new']
# 29.4 ms ± 1.08 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)


%timeit Series(map('_'.join, big.values.astype(str).tolist()), index=big.index)
# 27.4 ms ± 2.36 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)

Comparison against @derchambers answer (using their df data frame where all columns are strings):

from functools import reduce

def reduce_join(df, columns):
    slist = [df[x] for x in columns]
    return reduce(lambda x, y: x + '_' + y, slist[1:], slist[0])

def list_map(df, columns):
    return Series(
        map(
            '_'.join,
            df[columns].values.tolist()
        ),
        index=df.index
    )

%timeit df1 = reduce_join(df, list('1234'))
# 602 ms ± 39 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

%timeit df2 = list_map(df, list('1234'))
# 351 ms ± 12.1 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

Short associative function example:

public String getIcon(TipoNotificacao tipo)
{
    switch (tipo){
        case Comentou : return "fa fa-comments";
        case ConviteEnviou : return "icon-envelope";
        case ConviteAceitou : return "fa fa-bolt";
        default: return "";
    }
}

Like @Dhanushka said, omit the qualifier inside "switch" is the key.

I had problems to change attributes of text after that, and I could see others asking why...

So best answer is to use extension with NSMutableAttributedString instead:

extension String {

 var htmlToAttributedString: NSMutableAttributedString? {
    guard let data = data(using: .utf8) else { return nil }
    do {
        return try NSMutableAttributedString(data: data,
                                      options: [.documentType: NSMutableAttributedString.DocumentType.html,
                                                .characterEncoding: String.Encoding.utf8.rawValue],
                                      documentAttributes: nil)
    } catch let error as NSError {
        print(error.localizedDescription)
        return  nil
    }
 }

}

And then you can use it this way:

if let labelTextFormatted = text.htmlToAttributedString {
                let textAttributes = [
                    NSAttributedStringKey.foregroundColor: UIColor.white,
                    NSAttributedStringKey.font: UIFont.boldSystemFont(ofSize: 13)
                    ] as [NSAttributedStringKey: Any]
                labelTextFormatted.addAttributes(textAttributes, range: NSRange(location: 0, length: labelTextFormatted.length))
                self.contentText.attributedText = labelTextFormatted
            }

dumpbin from Visual Studio tools (VC\bin folder) can help here:

dumpbin /dependents your_dll_file.dll

Similar to @nayun oh answer above, but for older versions of Spring, use this code:

SpringApplication application = new SpringApplication(DemoApplication.class);
application.setApplicationContextClass(AnnotationConfigApplicationContext.class);
application.run(args);

you can use inner join :

DELETE 
    ps 
FROM 
    posts ps INNER JOIN 
         (SELECT 
           distinct id 
         FROM 
             posts 
         GROUP BY id  
      HAVING COUNT(id) > 1 ) dubids on dubids.id = ps.id  

If you wish to list all tables, you must use:

\dt *.*

to indicate that you want all tables in all schemas. This will include tables in pg_catalog, the system tables, and those in information_schema. There's no built-in way to say "all tables in all user-defined schemas"; you can, however, set your search_path to a list of all schemas of interest before running \dt.

You may want to do this programmatically, in which case psql backslash-commands won't do the job. This is where the INFORMATION_SCHEMA comes to the rescue. To list tables:

SELECT table_name FROM information_schema.tables WHERE table_schema = 'public';

BTW, if you ever want to see what psql is doing in response to a backslash command, run psql with the -E flag. eg:

$ psql -E regress    
regress=# \list
********* QUERY **********
SELECT d.datname as "Name",
       pg_catalog.pg_get_userbyid(d.datdba) as "Owner",
       pg_catalog.pg_encoding_to_char(d.encoding) as "Encoding",
       d.datcollate as "Collate",
       d.datctype as "Ctype",
       pg_catalog.array_to_string(d.datacl, E'\n') AS "Access privileges"
FROM pg_catalog.pg_database d
ORDER BY 1;
**************************

so you can see that psql is searching pg_catalog.pg_database when it gets a list of databases. Similarly, for tables within a given database:

SELECT n.nspname as "Schema",
  c.relname as "Name",
  CASE c.relkind WHEN 'r' THEN 'table' WHEN 'v' THEN 'view' WHEN 'i' THEN 'index' WHEN 'S' THEN 'sequence' WHEN 's' THEN 'special' WHEN 'f' THEN 'foreign table' END as "Type",
  pg_catalog.pg_get_userbyid(c.relowner) as "Owner"
FROM pg_catalog.pg_class c
     LEFT JOIN pg_catalog.pg_namespace n ON n.oid = c.relnamespace
WHERE c.relkind IN ('r','')
      AND n.nspname <> 'pg_catalog'
      AND n.nspname <> 'information_schema'
      AND n.nspname !~ '^pg_toast'
  AND pg_catalog.pg_table_is_visible(c.oid)
ORDER BY 1,2;

It's preferable to use the SQL-standard, portable INFORMATION_SCHEMA instead of the Pg system catalogs where possible, but sometimes you need Pg-specific information. In those cases it's fine to query the system catalogs directly, and psql -E can be a helpful guide for how to do so.

One of the reason may be if any one of table column have an underscore(_) in its name . That is considered as invalid characters by the JDBC . Rename the column by a ALTER Command and change in your code SQL , that will fix .

Use this script for redis >=5:

You can do something like this:

SELECT id,name, REPLACE(REPLACE(hide,0,"false"),1,"true") AS hide FROM your-table

Hope this can help you.

// sample data
$requiredKeys = ['key1', 'key2', 'key3'];
$arrayToValidate = ['key1' => 1, 'key2' => 2, 'key3' => 3];

function keysExist(array $requiredKeys, array $arrayToValidate) {
    if ($requiredKeys === array_keys($arrayToValidate)) {
        return true;
    }

    return false;
}

You can also use a proxy tool like Charles to capture the outgoing request headers, data, etc. by passing the proxy details through CURLOPT_PROXY to your curl_setopt_array method.

For example:

$proxy = '127.0.0.1:8888';
$opt = array (
    CURLOPT_URL => "http://www.example.com",
    CURLOPT_PROXY => $proxy,
    CURLOPT_POST => true,
    CURLOPT_VERBOSE => true,
    );

$ch = curl_init();
curl_setopt_array($ch, $opt);
curl_exec($ch);
curl_close($ch);

I know it's been a year since this was asked, but just for people that are going to visit this page I am posting my solution.

By using what @Aldi Unanto suggested here is a more complete answer:

  jQuery('.show_hide').click(function(e) {
    e.preventDefault();
    if (jQuery('.slidingDiv').is(":visible") ) {
      jQuery('.slidingDiv').stop(true,true).hide("slide", { direction: "left" }, 200);
    } else {
      jQuery('.slidingDiv').stop(true,true).show("slide", { direction: "left" }, 200);
    }
  });

First I prevent the link from doing anything on click. Then I add a check if the element is visible or not. When visible I hide it. When hidden I show it. You can change direction to left or right and duration from 200 ms to anything you like.

Edit: I have also added

.stop(true,true)

in order to clearQueue and jumpToEnd. Read about jQuery stop here

no it doesnt. break is for loops, not ifs.

nested if statements are just terrible. If you can avoid them, avoid them. Can you rewrite your code to be something like

if (c1 && c2) {
    //sequence 1
} else if (c3 && c2) {
   // sequence 3
}

that way you don't need any control logic to 'break out' of the loop.

Maybe you can use WebView, but as you can see in the doc WebView doesn't support javascript and other stuff like widgets by default.

http://developer.android.com/reference/android/webkit/WebView.html

I think that you can enable javascript if you need it.

I had a similar problem. I ended up nuking it from orbit, and lost my SVN history in the process. But at least I made that damn error go away.

This is probably a sub-optimal sequence of commands to execute, but it should fairly closely follow the sequence of commands that I actually did to get things to work:

cp -rp target ~/other/location/target-20111108
svn rm target --force
cp -rp ~/other/location/target-20111108 target-other-name
cd target-other-name
find . -name .svn -print | xargs rm -rf
cd ..
svn add target-other-name
svn ci -m "Re-re-re-re-re-re-re-re-re-re import target"
svn mv target-other-name target
svn ci -m "Re-re-re-re-re-re-re-re-re-re import target"

Option 1 - Android PCAP

Limitation

Android PCAP should work so long as:

Your device runs Android 4.0 or higher (or, in theory, the few devices which run Android 3.2). Earlier versions of Android do not have a USB Host API

Option 2 - TcpDump

Limitation

Phone should be rooted

Option 3 - bitshark (I would prefer this)

Limitation

Phone should be rooted

Reason - the generated PCAP files can be analyzed in WireShark which helps us in doing the analysis.

Other Options without rooting your phone

1. tPacketCapture

https://play.google.com/store/apps/details?id=jp.co.taosoftware.android.packetcapture&hl=en

Advantages

Using tPacketCapture is very easy, captured packet save into a PCAP file that can be easily analyzed by using a network protocol analyzer application such as Wireshark.

2. You can route your android mobile traffic to PC and capture the traffic in the desktop using any network sniffing tool.

If using a BeansWrapper with an exposure level of Expose.SAFE or Expose.ALL, then the standard Java approach of iterating the entry set can be employed:

For example, the following will work in Freemarker (since at least version 2.3.19):

<#list map.entrySet() as entry>  
  <input type="hidden" name="${entry.key}" value="${entry.value}" />
</#list>

In Struts2, for instance, an extension of the BeanWrapper is used with the exposure level defaulted to allow this manner of iteration.

In my case it got fixed by increasing the extended memory of eclipse, by changing the value of -Xmx768m in eclipse.ini

This could also happens if you put a @PreAuthorize or @PostAuthorize in a Bean in creation. I would recommend to move such annotations to methods of interest.

Using docker-compose, I accomplished this by creating a service that mounts the volumes that I need and committing the image of the container. Then, in the subsequent service, I rely on the previously committed image, which has all of the data stored at mounted locations. You will then have have to copy these files to their ultimate destination, as host mounted directories do not get committed when running a docker commit command

You don't have to use docker-compose to accomplish this, but it makes life a bit easier

# docker-compose.yml

version: '3'
  services:
    stage:
      image: alpine
      volumes:
        - /host/machine/path:/tmp/container/path
      command: bash -c "cp -r /tmp/container/path /final/container/path"
    setup:
      image: stage

# setup.sh

# Start "stage" service
docker-compose up stage

# Commit changes to an image named "stage"
docker commit $(docker-compose ps -q stage) stage

# Start setup service off of stage image
docker-compose up setup

Consider if instead it was:

class RectangularRoom(object):
    def __init__(self, width, height):
        pass

    def cleanTileAtPosition(self, pos):
        pass

    def isTileCleaned(self, m, n):
        pass

and you subclass and forget to tell it how to isTileCleaned() or, perhaps more likely, typo it as isTileCLeaned(). Then in your code, you'll get a None when you call it.

• Will you get the overridden function you wanted? Definitely not.
• Is None valid output? Who knows.
• Is that intended behavior? Almost certainly not.
• Will you get an error? It depends.

raise NotImplmentedError forces you to implement it, as it will throw an exception when you try to run it until you do so. This removes a lot of silent errors. It's similar to why a bare except is almost never a good idea: because people make mistakes and this makes sure they aren't swept under the rug.

Note: Using an abstract base class, as other answers have mentioned, is better still, as then the errors are frontloaded and the program won't run until you implement them (with NotImplementedError, it will only throw an exception if actually called).

Jbuilder is a gem built by rails community. But it works well in non-rails environments and have a cool set of features.

# suppose we have a sample object as below
sampleObj.name #=> foo
sampleObj.last_name #=> bar

# using jbuilder we can convert it to json:
Jbuilder.encode do |json|
  json.name sampleObj.name
  json.last_name sampleObj.last_name
end #=> "{:\"name\" => \"foo\", :\"last_name\" => \"bar\"}"

From MySQL docs:

A character set is a set of symbols and encodings. A collation is a set of rules for comparing characters in a character set. Let's make the distinction clear with an example of an imaginary character set.

Suppose that we have an alphabet with four letters: 'A', 'B', 'a', 'b'. We give each letter a number: 'A' = 0, 'B' = 1, 'a' = 2, 'b' = 3. The letter 'A' is a symbol, the number 0 is the encoding for 'A', and the combination of all four letters and their encodings is a character set.

Now, suppose that we want to compare two string values, 'A' and 'B'. The simplest way to do this is to look at the encodings: 0 for 'A' and 1 for 'B'. Because 0 is less than 1, we say 'A' is less than 'B'. Now, what we've just done is apply a collation to our character set. The collation is a set of rules (only one rule in this case): "compare the encodings." We call this simplest of all possible collations a binary collation.

But what if we want to say that the lowercase and uppercase letters are equivalent? Then we would have at least two rules: (1) treat the lowercase letters 'a' and 'b' as equivalent to 'A' and 'B'; (2) then compare the encodings. We call this a case-insensitive collation. It's a little more complex than a binary collation.

In real life, most character sets have many characters: not just 'A' and 'B' but whole alphabets, sometimes multiple alphabets or eastern writing systems with thousands of characters, along with many special symbols and punctuation marks. Also in real life, most collations have many rules: not just case insensitivity but also accent insensitivity (an "accent" is a mark attached to a character as in German 'ö') and multiple-character mappings (such as the rule that 'ö' = 'OE' in one of the two German collations).
